Can I use Mojopedals to control instruments and sound modules of another brand?

Yes, of course! Mojopedals is perfectly compatible with devices able to recognize MIDI messages. Crumar Mojopedals sends out MIDI NOTE ON/OFF messages, you can change MIDI channels, you can select the octave and transpose and you can send out MIDI program change messages. You can plug a volume or an expression pedals to the "expression pedal in" and you will have MIDI CC#4 or 7 or 11 messages sent out.
